Abstract
PURPOSE:To enhance the operating efficiency and accuracy of a linear motor by forming the width of a frame-shaped coil forming a stator at the value odd number of times of the width of the magnetic pole of a movable element and containing a position detector at the position isolated at the width of the magnetic pole of the movable element from the side of the coil in the hollow part of the coil. CONSTITUTION:In a linear motor in which the primary side stator is formed of a frame-shaped coil 3 and the secondary side movable element is formed of a magnet 11, the width of the coil 3 is formed odd-fold of the width T of the magnetic pole of the magnet 11. A position detecting circuit 5 including a position detector 4 for detecting the position of the magnet is contained in the inside hollow part 3a of the coil 3, and in this case the position of the detector 4 is disposed at the position isolated in the width T of the magnetic pole of the magnet 11 from the side of the coil. The coil 3 and the detecting circuit 5 are molded with plastic material and are integrated in a long plate shape to form a stator 1.
